Found it in a discount bin, has grown beautifully in part sun and deep shade. The one plant is now five.I have it next to a rue - it covers the ugly knees and matches the colour exactly, so the foliage shape contrast is highlighted.
One of my favorites

A fast grower but a bit slow to spread. It look good in the middle of a medium to large hosta patch. It will held up its blue color through most of the year and will grow in woodland shade.

In my garden on the border of zone 3/4, this hosta has been very reliable. It is not a fast grower, but it steadily increases.

The powdery blue color of the leaves and its upright, vase shape make it a nice contrast to the greener, lower hosta.

Positive northgrass On Mar 2, 2005, northgrass from West Chazy, NY (Zone 4b) wrote:

This one is at the top of my list. Lovely blue color lasting late in the season if grown in part shade. Beautifully vase shaped. Even the blossoms look quite impressive, so tall.

Positive smiln32 On May 26, 2003, smiln32 from Oklahoma City, OK (Zone 7a) wrote:

Mine is not an especially fast grower, but I think that has to do with a shorter dormancy period here in the south. It has rich color and upright habit, making it a lovely counterpart to moundlike hostas.

Although the foliage is lovely I cannot get my Krossa Regal to flower - one is in pretty deep shade and the other in moderate shade. Any answers?

Part Sun Best

Positive lupinelover On May 7, 2002, lupinelover from Grove City, OH (Zone 6a) wrote:

Due to the upright growth of this variety, it almost never has had slug damage in any garden I have seen.

If grown in full shade, blue color remains through most of year.

Positive Greenwood On May 7, 2002, Greenwood from Bonifay, FL (Zone 8a) wrote:

Krossa Regal starts the season with powdery blue foliage by mid summer the vase shaped mound turns dark green. The flowering habits are notable with scapes 3' to 6' tall.
